Theo Verelst Fosdem 2004 Page

I recently was at the belgium Fosdem open source conference in Brussels, the european community headquarters city, at the University Libre the Brussels.

Nice experience, and I gave two talks, one at the Tcl/Tk developers room with several core team members present, about BWise, and one bigger audience 'Lightning' short talk about my string simulator, with succesfull audio demonstration through my portable PA system.

I've made a page on the string simulator, these are slides (in openoffice 1.0 presenter format) , here is a very short mpeg audio example, and also the full, actual quality audio demo in 16 bit stereo 44.1kHz wav format I fed to my portable audio system via a high quality USB DA converter (which I brought along in a metal cookie box for shielding).

I and the owner of the camera have made video registrations, mostly of the TCL developers room, in principle of decent quality, though I sinned against the rules of good sound setup and good lighting. The beamer was 1024x768, which for the presentation was better than I had hoped for, but is not so easy to capture even with digital video, and even more when some space around it with the speaker is in the picture, and especially after webserver-bandwidth encoding of the video...

Thus far I've made a few digital, downloadable versions of some of the video tapes, which are of incomparable higher quality, compressed to be viewable without directly over the local server upload bandwidth by one viewer at the time:

tape 1 part of Clif Flynt, Intro to Tcl/Tk, and Theo Verelst (me!) first part of BWise, a blockwise tcl and tk-canvas based scripting approach (Windows Media File, approx. 1 hour, 210kb/s, total 88.9MB)

tape 2 Theo Verelst (me!) second part of BWise, a blockwise tcl and tk-canvas based scripting approach, followed by Jeff Hobbs, The (Active) State of Tcl/Tk (Windows Media File, approx. 1 hour, 210kb/s, total 94.1MB)

tape 3 Clif Flynt, Writing a Tcl Extension (Windows Media File, approx. 1 hour, 210kb/s, total 93.8MB)

tape 4 part of Clif Flynt, Embedding Tcl/Tk within a C program, Lightning talk Theo Verelst (me) mathematical (e.g. guitar) strings simulation with audio, Andrea Glorioso Agnula Libre Software for Audio/Video (Windows Media File, approx. 1 hour, 210kb/s, total 79.3MB)

tape 5 Peter De Rijk, Making applications with the ClassyTk gui builder (Windows Media File, approx. 1 hour, 210kb/s, total 78.4MB)

tape 6 Arjen Markus, Several applications of Tk's powerful text widget are shown (Windows Media File, approx. 1 hour, 210kb/s, total 51.5MB)

tape 7 Tcl/Tk Developers room final discussion, only a few minutes was taped ... (Windows Media File, approx. 1 hour, 210kb/s, total 1.1MB)

piece 7b Tcl/Tk Developers room final discussion II, only a limited time ended up on memorystick ... (MPG format, total 42.8MB)

Mind that either you need to right-click-->save, or copy URL and paste in the (media) player's FILE-->'Open URL' box to make this work. The mime type isn't in the server, or something, so simple click doesn't start the player automatically. On linux, a recent mplayer should be able to (inmaybe even higher quality) player these files, and I guess mplayer is possible on the Mac, too (It's been a long time since I used macs). These are unedited and unprocessed files.

(just for these days, while I'm encoding the tapes, 'live' viewing along is possible with a window media player compatible player via url: mms:// )

Fortune of the day
(it just happened to come up while I made this page):

   The assertion that "all men are created equal" was of no practical use
   in effecting our separation from Great Britain and it was placed in the
   Declaration not for that, but for future use.

When I tried the above link, I got this one:
